I boot my test systems all of the time without keyboard, mouse, or
monitor & then VNC amongst the machines (Hardy, Intrepid & Jaunty) to do
testing. In order to do that I have autologin enabled:
System|Administration|Security|Enable Automatic Login - checked. Give
that a try & post back (bottom post please :-) the results.

Note: there are other methods (Secure Remote Connection etc), but
autologin is probably the easiest.
